It's a track car! No, it's street legal! Wait, it's both — it's the 2008 Dodge Viper SRT10 ACR and it'll be making its debut in just under a week at the LA Auto Show. We were going to wait until midnight tonight to show off the lighter Viper package — a package not seen for the Viper since 1999. Seriously, we were going to hold off on showing off the details on the 600 horses and 560 lb-ft of torque coming from the gigantic 8.4-liter V10 engine in this purpose-built, street-legal track car. But — we figured since AutoWeek can't seem to keep their snake in their pockets, why should we? This new edition of the already quite deadlypotent serpentine super car features added aerodynamic enhancements, an enhanced racing suspension and weight savings from the "base model" '08 Viper. In addition to the 40 lbs in weight savings you'll see with the base level ACR package, you'll also have the option of a "hard core" audio delete option that will drop the audio system, underhood silencer pad, trunk carpet and tire inflator. With this package, the radio is replaced by a lightweight cover that can be configured to mount an included lap timer and the door speakers are replaced by lightweight carbon-fiber panels. The "hard core" package drops the weight by another 40 lbs. Oh wait, and did we mention it comes in new colors? Like Viper Red, Viper Black, Viper Violet, Viper Bright Blue Metallic, and Viper Very Orange. We hear the next edition will come in Viper Puce Green. Full press release with all the gory details below the jump.

Auburn Hills, Mich. - Dodge announced today that the all-new 2008 Dodge Viper SRT10® ACR - short for American Club Racer - will make its public debut at next week's Los Angeles Auto Show.

The latest addition to Chrysler LLC's Street and Racing Technology (SRT) family of performance vehicles, the all-new, 600-horsepower 2008 Dodge Viper SRT10 ACR is a street-legal Viper engineered to dominate on the race track. Because it is street legal, diehard Viper and track enthusiasts can drive their car to the race track, run it at speed on the track, and then drive it home.

"With the all-new 2008 Dodge Viper SRT10 ACR, SRT has taken the ultimate American sports car and injected it with an extra dose of racing DNA," said Mike Accavitti, Director - Dodge Brand and SRT Marketing and Communications, Chrysler LLC. "With the Viper SRT10 as the starting point, SRT engineered a combination of reduced weight, race-tuned suspension and aerodynamic improvements to create the ultimate Viper for the street and track."

Derived from the all-new 2008 Dodge Viper SRT10, the heart and soul of the all-new 2008 Viper SRT10 ACR is SRT's new 8.4-liter aluminum V-10 engine that produces 600 horsepower and 560 lb.-ft. of torque.

The 2008 Dodge Viper SRT10 ACR exterior styling cues offer not only bold aesthetics but functional benefits on the track. These include a variable geometry "fanged" front splitter, an adjustable rear wing sculpted by CFD (Computational Fluid Dynamics), and optimized front dive planes. These new aerodynamic devices are formed in high-performance autoclaved carbonfiber. By using both unidirectional and woven laminates, the aero equipment is optimized for the minimum possible weight.

The front splitter includes three removable rub strips that provide protection and wear resistance. Supported by stainless steel tension cables, the splitter is designed to absorb the energy from minor upward deflections.

The Dodge Viper SRT10 ACR aerodynamics are tuned and balanced to maximize downforce and provide increased levels of lateral grip. Each Viper SRT10 ACR also includes a track extension that replaces the center splitter rub strip and fills out the fanged splitter scallop for closed-circuit events. The aerodynamic effect of the track extension is a reduction in overall drag and an increase in front downforce of nearly one third.

The front fog lamps have been deleted and replaced with lightweight filler panels.

The 2008 Viper SRT10 ACR features a signature two-tone paint scheme with a black center section. An optional driver's stripe is available on a two-tone Viper Red or a Viper Black ACR. The driver's stripe also features a sewn leather accent on the steering wheel. A clearcoated exposed weave is featured on the rear carbonfiber wing of all two-tone and driver's stripe Viper SRT10 ACR models.

Based on the 2008 Viper SRT10 interior, the Viper SRT10 ACR goes a step further to satisfy what racers want: the least weight possible. An optional "Hard Core" package offers maximum weight savings by deleting the audio system, underhood silencer pad, trunk carpet and tire inflator. The radio is replaced by a lightweight cover that can be configured to mount the included lap timer. The door speakers are replaced by lightweight carbonfiber panels. The Hard Core package offers a 40 lb. weight savings and provides ultimate street legal race-ready performance.

World-class Ride and Handling

The all-new 2008 Dodge Viper SRT10 ACR is specifically modified and tuned for track performance. The ACR suspension includes coil-over racing dampers from KW Suspensions that are adjustable for damping and ride height. The shocks are two-way adjustable without removing the wheels - a timesaver on the track - and they include a large range for compression and rebound. The KW dampers and forks are machined from solid aluminum billet, feature spherical bearing mounts, and are optimized to minimize weight and maximize performance.

The 2008 Dodge Viper SRT10 ACR features a new front stabilizer bar for increased roll-stiffness.

Track performance is maximized in the 2008 Dodge Viper SRT10 ACR via several weight-savings initiatives. The savings were achieved with the Michelin Pilot Sport Cup Tires, Sidewinder lightweight wheels, and StopTech brake rotors. With the aerodynamic and suspension elements, the 2008 Dodge Viper SRT10 ACR is 40 pounds lighter than the Viper SRT10 coupe. The optional Hard Core package further reduces the weight by another 40 pounds, for a total weight savings of 80 pounds.

The 2008 Dodge Viper SRT10 ACR utilizes the Viper SRT10's new 8.4-liter aluminum V-10 engine that produces a ground-shaking 600 horsepower and tire-smoking 560 lb.-ft. of torque. It features a deep-skirted V10 aluminum engine block, cylinder heads equipped with Computer Numerically Controlled (CNC)-shaped combustion chambers, large valves and Variable Valve Timing (VVT). VVT Electronically adjusts when the exhaust valves are open and closed according to engine speed and load, allowing the engine to "breathe" cleaner and more efficiently.

The two-piece intake manifold combines cast aluminum lower with smooth runners for better air flow, bolted to a die-cast aluminum upper plenum. A revised air-cleaner box with a low-restriction filter sends air through a dual electronic throttle control into the intake module.

The air-fuel mixture in the cylinders is ignited by platinum-tip spark plugs fired by individual plug coils mounted on the cylinder-head covers.

Within the cylinders, pistons are equipped with large-diameter floating pins with bronze bushings for high-load capability. Forged powder-metal connecting rods are secured with aircraft-quality fasteners for increased fatigue strength.

Engine lubrication is managed by the large oil pump and a swinging oil pickup adapted from Viper competition engines, to ensure proper oil pressure in high-rpm and hard cornering conditions.

The 2008 Dodge Viper SRT10 ACR sports the latest evolution of the Tremec T56 six-speed manual transmission known as the TR6060. Power is transmitted to the rear wheels via a GKN ViscoLok speed-sensing limited-slip differential.

Manufacturing

The 2008 Dodge Viper SRT10 ACR will be hand built at the Conner Avenue Assembly Plant in Detroit.

The 2008 Dodge Viper SRT10 ACR will arrive in showrooms in the second quarter of 2008 at a Manufacturer's Suggested Retail Price (MSRP) of less than $100,000. Complete pricing information will be released at a later date.
